Hello,
My 2015 S6 developed an engine fault yesterday and limited the revs to 4000. I have a basic code reader which gave P0021 and P0018 which I believe are related to the crankshaft sensor. The car has done 51k and is standard.
The car drives totally fine except for the warning lights and lower rev limit.
My usual mechanic had a look at it today and took it to an Audi diagnostic specialist who said it's actually a correlation error between the camshaft sensor and the crankshaft sensor. I think he said Bank 2 sensor A but I could be wrong, but it's definitely just one bank.
My mechanic recommended I try an Audi specialist for a repair so my first question is can anyone recommend anyone in the northwest? Particularly in the Manchester or south Lancashire area?
I have phoned Volkmaster in Bury as they are probably the closest. Without seeing the car they were talking about potentially replacing all 4 cam chains and a bill of between £2.5k and £4k and engine out.
I've got a list of other garages to phone tomorrow but I'd like to get some recommendations if I can.
I did find this post where someone in the US had the same issue but seemed to get a cheaper fix?

Any help gratefully appreciated.
Thanks
